A method has been developed to determine cobalt by oxidizing cobaltous ion to cobaltic ion and precipitating cobaltic 1-nitroso-2-naphtholate from homogeneous solution by synthesizing the reagent within the reaction mixture. Excess reagent precipitates after the cobalt nitroso-naphtholate has settled. A washing procedure has been developed to eliminate the excess reagent without affecting the cobalt nitroso-naphtholate. After washing to remove excess reagent and filtration, the precipitate is dried and weighed as Co(C10H6NO2)3•2H2O. [TRUNCATE]
